You can boost the 35% to torpedo fuel by freezing out the water...
I wouldn’t recommend it, this is the T-Stoff that dissolved more than one Me-163 pilot in his seat...
Agree on the rocket fuel angle. The 35% available is more than potent, usually thinned with distilled water for a working strength sterilant. The problem is finding a percentage solution with sufficient working time in contact with a surface, as decomposition immediately sets in.
